Pygmalion Users Manual

摘要

PYGMALION (or Pygi for short) is a RELAP5 utility program that updates theinitial condition information within a RELAP5 input file. These initial conditions are obtained by performing steady-state calculations, the final results of which are written to a restart/plot (rstplt) file for subsequent use. Pygi accesses the rstplt file, obtains the final conditions for each component of the system model, and replaces the appropriate cards in the original input file with cards containing the new conditions. The new input file then accurately represents the hydrodynamic state of the problem as it was at the end of the steady-state initialization run.
